First step was a HackerRank which wasn't too difficult. Then had an interview where the interviewer asked very in-depth questions about Javascript (e.g. about the interpreter), which was out of left field because I was not told this was a technical interview (and the questions were very advanced for an internship position). They followed up 2 months later to schedule another interview which was again a technical interview but I was not told this. I was asked to build a frontend project in an hour, but it had been 6 months since I had used the specific tech they were working with (and I was not told to prepare this), so I struggled. I was very unhappy as I invested a lot of time into interviewing (total of 4 hours) but the company took months for the interview process and did not give any information on what I could expect in the interview
